[0002] The toner cartridge is an important component in laser printers or copiers, consisting of an aluminum cylinder and photosensitive material. Its function is to use light to turn the content to be printed into an electrostatic image, then attract toner, and finally transfer the toner onto the paper to achieve the printing purpose. However, after prolonged use, existing toner cartridges accumulate a lot of waste toner inside, which is difficult to remove, and long-term accumulation will affect the overall lifespan of the toner cartridge. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a toner cartridge that is easy to clean up waste toner, which has the advantage of being able to clean up waste toner in a fast-moving manner.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a toner cartridge that facilitates waste powder cleaning, comprising a toner cartridge, a connecting block fixedly installed at the bottom of the toner cartridge, a magnetic roller rotatably connected inside the connecting block, a protective plate fixedly installed on the right side of the toner cartridge, an air duct fixedly installed in the middle of the toner cartridge and the protective plate, a ventilation chamber fixedly installed on the right side of the air duct, and a miniature air pump fixedly installed above the ventilation chamber.

[0005] As a preferred embodiment of this utility model, a fixing block is fixedly installed at the bottom of the drum, and an OPC roller is provided at the bottom of the drum. A limiting piece 1 is fixedly installed on the side of the OPC roller near the fixing block, and a telescopic rod 1 is fixedly installed on the side of the limiting piece 1 near the fixing block. A spring 1 is fixedly installed on the outer side of the telescopic rod 1, and a limiting piece 2 is fixedly installed on the outer side of the telescopic rod 1. The limiting piece 2 is located on the left side of the fixing block, and the limiting piece 2 is rotatably connected to the fixing block.

[0006] As a preferred technical solution of this utility model, the right side of the toner cartridge has a waste powder outlet, the inside of the waste powder outlet has a sealing cover, and mounting plates are fixedly installed on both the upper and lower sides of the sealing cover. Screws are engaged inside the mounting plates, and the screws engage with the toner cartridge.

[0007] As a preferred embodiment of this utility model, the top of the toner cartridge is provided with a toner filling port, a fixing plate is fixedly installed above the toner cartridge, a telescopic rod is fixedly installed on the left side of the fixing plate, a spring is sleeved on the outer side of the telescopic rod, a connecting plate is fixedly installed on the side of the spring away from the fixing plate, and a sealing plate is fixedly installed at the bottom of the connecting plate.

[0008] As a preferred embodiment of this utility model, there are multiple air ducts, all of which are located on the right side of the toner cartridge and are arranged in a parallel front-to-back pattern.

[0009] As a preferred embodiment of this utility model, there are two fixing blocks, which are located on the left and right sides of the OPC roller respectively. The OPC roller is a cylinder, and the diameter of the OPC roller is larger than the diameter of the magnetic roller.

[0010] As a preferred embodiment of this utility model, there are two of each of the fixed plate, telescopic rod two, and spring two, with both telescopic rod two and spring two located on the right side of the connecting plate.

[0011] As a preferred embodiment of this utility model, there are two springs and two limiting plates, with the two springs and the two limiting plates located on the left and right sides of the OPC roller, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a protective plate fixedly installed on the right side of the toner cartridge, an air duct fixedly installed in the middle of the toner cartridge and the protective plate, a ventilation chamber fixedly installed on the right side of the air duct, and a miniature air pump fixedly installed above the ventilation chamber. When waste powder inside the toner cartridge needs to be processed, the miniature air pump is first started to inject gas into the ventilation chamber. The gas then enters the air duct through the ventilation chamber. Since the air duct is fixedly installed to the toner cartridge and the air duct passes through the left side of the toner cartridge and connects to the inside of the toner cartridge, and since the waste powder inside the toner cartridge remains dry and fine, the waste powder inside the toner cartridge is easily blown out from right to left by the gas, thus facilitating the cleaning of the waste powder.

[0014] 2. This utility model features a limiting plate 1 fixedly installed on the side of the OPC roller near the fixed block, a telescopic rod 1 fixedly installed on the side of the limiting plate 1 near the fixed block, a spring 1 fixedly installed on the outside of the telescopic rod 1, and a limiting plate 2 fixedly installed on the outside of the telescopic rod 1. The limiting plate 2 is located on the left side of the fixed block and is rotatably connected to the fixed block. After the OPC roller has been working for a long time, carbon powder will inevitably accumulate on its surface, requiring disassembly for maintenance and replacement. However, existing OPC rollers are difficult to install and disassemble. When maintenance is required, the telescopic rod 1 is pressed towards the limiting plate 1. At this time, the telescopic rod 1 can retract. When the end of the telescopic rod 1 away from the limiting plate 1 is disengaged from the inside of the fixed block, the OPC roller will fall into the drum due to the fixed connection between the spring 1 and the telescopic rod 1, thus achieving the effect of convenient disassembly and maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a toner cartridge that is easy to clean waste powder, including a toner cartridge 1, a connecting block 2 fixedly installed at the bottom of the toner cartridge 1, a magnetic roller 3 rotatably connected inside the connecting block 2, a protective plate 4 fixedly installed on the right side of the toner cartridge 1, an air duct 5 fixedly installed in the middle of the toner cartridge 1 and the protective plate 4, a ventilation chamber 6 fixedly installed on the right side of the air duct 5, and a miniature air pump 7 fixedly installed above the ventilation chamber 6.

[0024] When it is necessary to process the waste powder inside the toner cartridge 1, first start the micro air pump 7 to inject gas into the ventilation chamber 6. At this time, the gas enters the air duct 5 through the ventilation chamber 6. Since the air duct 5 is fixedly installed with the toner cartridge 1 and the inside of the air duct 5 passes through the left side of the toner cartridge 1 and connects with the inside of the toner cartridge 1, and since the waste powder inside the toner cartridge 1 is always kept dry and fine, the waste powder inside the toner cartridge 1 is easily blown out from right to left by the gas, thus facilitating the cleaning of the waste powder.

[0025] The drum unit 1 has a fixed block 8 at its bottom and an OPC roller 9 at its bottom. A limiting piece 10 is fixedly installed on the side of the OPC roller 9 near the fixed block 8. A telescopic rod 11 is fixedly installed on the side of the limiting piece 10 near the fixed block 8. A spring 12 is fixedly installed on the outside of the telescopic rod 11. A limiting piece 2 13 is fixedly installed on the outside of the telescopic rod 11. The limiting piece 2 13 is located on the left side of the fixed block 8 and is rotatably connected to the fixed block 8.

[0026] After prolonged operation, OPC roller 9 inevitably accumulates toner powder on its surface, requiring disassembly for maintenance and replacement. However, the existing OPC roller 9 is difficult to disassemble due to its cumbersome installation. When maintenance is needed, the telescopic rod 11 is pressed towards the limiting plate 10. Since the telescopic rod 11 can retract, when the end of the telescopic rod 11 away from the limiting plate 10 disengages from the fixing block 8, the OPC roller 9 will fall into the drum 1 because it is fixedly connected to the telescopic rod 11 by the spring 12. This facilitates disassembly and maintenance.

[0027] The drum unit 1 has a waste toner outlet 14 on its right side. The waste toner outlet 14 has a sealing cover 15 inside. Mounting plates 16 are fixedly installed on both the upper and lower sides of the sealing cover 15. Screws 17 are engaged inside the mounting plates 16 and engage with the drum unit 1.

[0028] When the device is in operation, the sealing cover 15 is fixed inside the waste powder outlet 14 by the engagement of the mounting plate 16 and the screw 17, so that the waste powder outlet 14 is sealed to prevent powder leakage. When the waste powder needs to be cleaned, first remove the screw 17, and then remove the sealing cover 15 from the inside of the waste powder outlet 14. After placing the entire drum 1 into the sealed space, align the waste powder outlet 14 with the garbage bag. At this time, start the micro air pump 7 to blow air from the inside of the ventilation chamber 6 and the air duct 5, so that the waste powder is blown out from the inside of the drum 1 to the garbage can, so as to facilitate the cleaning of waste powder.

[0029] The drum unit 1 has a toner filling port 18 on its top. A fixing plate 19 is fixedly installed on the top of the drum unit 1. A telescopic rod 20 is fixedly installed on the left side of the fixing plate 19. A spring 21 is sleeved on the outside of the telescopic rod 20. A connecting plate 22 is fixedly installed on the side of the spring 21 away from the fixing plate 19. A sealing plate 23 is fixedly installed at the bottom of the connecting plate 22.

[0030] When it is necessary to add toner to the inside of the drum 1, first push the connecting plate 22 towards the fixed plate 19. At this time, the telescopic rod 20 and the spring 21 will retract, so that the toner filling port 18 is opened, thereby achieving the effect of adding toner.

[0031] There are multiple air ducts 5, all of which are located on the right side of the drum 1, and are distributed in parallel front to back.

[0032] Multiple air ducts 5 are fixedly connected to the ventilation chamber 6. When the micro air pump 7 is started to blow gas into the interior of the air duct 5, the interior of the toner cartridge 1 will be blown evenly, and the waste powder inside the toner cartridge 1 will be blown out evenly.

[0033] There are two fixing blocks 8, which are located on the left and right sides of the OPC roller 9 respectively. The OPC roller 9 is a cylinder and its diameter is greater than that of the magnetic roller 3.

[0034] The main function of the OPC roller 9 is to facilitate the adsorption of toner ions, thereby bonding it with the paper to achieve the printing effect.

[0035] There are two of each of the fixed plate 19, telescopic rod 20, and spring 21, with the two telescopic rods 20 and the two springs 21 located on the right side of the connecting plate 22.

[0036] The two springs 21 will always provide elastic force to push the two connecting plates 22 by the two telescopic rods 20, so that the two connecting plates 22 will always be in contact with the drum 1. Since the two connecting plates 22 are fixedly connected to the sealing plate 23, the filling port 18 will always be sealed when no toner needs to be added.

[0037] There are two springs 12 and two limit plates 13, with the two springs 12 and the two limit plates 13 located on the left and right sides of the OPC roller 9, respectively.

[0038] The diameters of the two springs 12 and the two limiting plates 13 are all greater than the internal diameter of the fixed block 8. The main function of the two limiting plates 13 is to limit the telescopic rod 11, so that the telescopic rod 11 can be easily inserted into the fixed block 8 and can be easily rotated and connected with the fixed block 8.

[0039] Working principle and usage process of this utility model:

[0040] First, a protective plate 4 is fixedly installed on the right side of the drum 1. An air duct 5 is fixedly installed in the middle of the drum 1 and the protective plate 4. A ventilation chamber 6 is fixedly installed on the right side of the air duct 5. A micro air pump 7 is fixedly installed above the ventilation chamber 6. When it is necessary to process the waste powder inside the drum 1, the micro air pump 7 is first started to inject gas into the ventilation chamber 6. At this time, the gas enters the air duct 5 through the ventilation chamber 6. Since the air duct 5 is fixedly installed with the drum 1 and the inside of the air duct 5 passes through the left side of the drum 1 and connects with the inside of the drum 1, and since the waste powder inside the drum 1 is always kept dry and fine, the waste powder inside the drum 1 is easily blown out from right to left by the gas, thus facilitating the cleaning of the waste powder.

[0041] Secondly, after the OPC roller 9 has been working for a long time, carbon powder will inevitably accumulate on its surface. At the same time, the OPC roller 9 needs to be disassembled for maintenance and replacement. However, the existing OPC roller 9 is difficult to disassemble because the installation is relatively complicated. When the OPC roller 9 needs to be maintained, press the telescopic rod 11 towards the limiting plate 10. At this time, since the telescopic rod 11 can retract, when the end of the telescopic rod 11 away from the limiting plate 10 is separated from the inside of the fixing block 8, the OPC roller 9 will fall out of the inside of the drum 1 because the OPC roller 9 is fixedly connected to the telescopic rod 11 by the spring 12. This achieves the effect of convenient disassembly and maintenance.

[0042] Meanwhile, a fixing plate 19 is fixedly installed on the top of the drum 1, and a telescopic rod 20 is fixedly installed on the left side of the fixing plate 19. A spring 21 is sleeved on the outside of the telescopic rod 20, and a connecting plate 22 is fixedly installed on the side of the spring 21 away from the fixing plate 19. A sealing plate 23 is fixedly installed at the bottom of the connecting plate 22. When it is necessary to add toner to the inside of the drum 1, the connecting plate 22 is first pushed towards the fixing plate 19. At this time, the telescopic rod 20 and the spring 21 will retract, so that the toner filling port 18 is opened, thereby achieving the effect of adding toner.

[0043] Finally, the second spring 21 will always provide elastic force to push the connecting plate 22 by the telescopic rod 20, so that the connecting plate 22 will always be in contact with the drum 1. Since the connecting plate 22 and the sealing plate 23 are fixedly connected, the powder filling port 18 will always be sealed when no powder filling is required.
